Abstract (en)
An electroluminescent device includes an anode, a positive-hole transporting layer made of an organic compound, a fluorescent emitting layer made of an organic compound, a cathode. The fluorescent emitting layer includes a red light emitting material uniformly dispersed in a host emitting material. The host emitting material being adapted to emit in the blue green regions so that the light produced by this device is substantially white. <IMAGE>
